Taylor Swift treated a young boy battling cancer to a private performance during her visit to Boston Children's Hospital over the weekend. The singer chatted with Jordan Lee Nickerson about Play-Doh and Spiderman before singing him "We Are Never Ever Getting Back Together." It doesn't take long before the 6-year-old started dancing and singing along. Swift has previously surprised patients at Hasbro Children's Hospital in Rhode Island, visited children suffering from cancer in New York, and bonded with leukemia patient Lauren Hacker.
